CHARLES J. SGHUMAOHER, OF PORTLAND, MAINE.

IMPROVEMENT I N MOTORS.

Specification forming part of Letters Patent No. 131,631, dated September 24, 1872.

To all whom it may concern:

Be it known that I, CHARLES J. Seno- MAGHER, of Portland, in the county of .Oum-

berland-and State of Maine, have invented a new and useful Improvement in Motors, of which the followingis a specification:

' This invention relates to an apparatus for storing up power for driving sewing-machines and other light machinery; and it consists in a series of spiral springs arranged on stationary spindles and revolved by means of gearing and crank, the construction and arrangement of parts being as hereinafter described.

In the accompanying drawing, Figure l is a top or plan view of the machine, partly in section. Fig.2 is a vertical cross-section of Fig. 1 taken on the line was, with a' part broken away. Fig. 3 is a detail, showing the drivingwheels in their proper positions at one end of the machine.

Similar letters of reference indicate correspondin g parts.

A is the driving-shaft, and B is the crank I by which the machine is wound up. 0 and D are bevel 0r miter gears, the former being on V the end of the shaft A, and the latter is connected with the spring E. In this example of m y invention I employ four springs, but I do not confine myself to any particular number. F represents stationary spindles or rods confined. by the heads G G of the machine. H is a bed-plate, to which the heads are attached. The driving-shaftAis connected with the head G. The four springs are parallel with each other,each being supported on a rod or spin- I. dle, as represented. J J are spur-wheels on As before stated, the power is first imparted to the spring E by means of the bevel-gears G and l), the latter being connected with the spring E. From the spring E the power is imparted to the spring 0 directly beneath by means of the spur-wheels J J. At the other end of the machine the spur-wheels K K mesh together, which conveys the power to the spring 1?, and from the springP it is imparted to the upper spring Q by the wheels at the opposite end of the machine. The upper spring Q carries thepower to the large spur-wheel L.

In applying this piece of mechanism to a sewing-machine or similar piece of machinery the large wheel L is geared with or attached to such machine.

S is a ratchet-wheelon the back of the bevelwheel D, and T is a pawl which en gages therewith, attached to the head G, by means of which the strain or torsion which has been imparted to the spring and conveyed from one to the other is retained as long as may be desired.

The power thus stored up can be renewed while the sewing-machine is running, so that no time need be lost in winding up or supplying the power.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A machine for imparting power and motion,.composed of spiral springs, spindles, and gear-wheels, when the same are arranged to operate substantially as described.

2. The rollers or cylinders N, in combination with the spindles F and springs E Q and P O, as and forthe purpose described.

3. The arrangement of the shaft A, bevelwheels 0 D, spur-wheels J J and J J, K K, and L, spindles F, heads G G, and rollers N, as and for the purposes described.
